摘　　要：研究了LLDPE g GMA (甲基丙烯酸缩水甘油酯 )对PA66/PE相容性的影响。结果表明LLDPE g GMA是PA66/PE合金良好的反应型增容剂 ,对于PA66/PE合金 ,LLDPE g GMA的加入使合金的拉伸强度、弯曲强度、Izod缺口冲击强度有明显提高。但刚性和耐热性略有降低 ,并且DMA谱图证实了LLDPE g GMA对PA66/PE的反应增容作用 。Studies on the effects of LLDPE g GMA on the compatibility of PA66/PE were made The results indicated that LLDPE g GMA was a good reactive compatibilizer for PA66/PE alloy The tensile strength,flexural strength and impact strength were significantly improved by adding LLDPE g GMA,but the rigidity and heat resistance decreased appreciably Meanwhile,the DMA spectrum proved the reactive compatibilization of LLDPE g GMA The transition activation energy of PA66/PE was also figured out
